Fig. 10. A 3.5 mm. embryo possessing 13 somites

A. A 3.5 mm. embryo possessing 13 somites and representing the middle part of the fourth week of development. The amnion has been removed so that the approximation of the bodystalk and omphalo-mesenteric duct are less evident than in Fig. 11. This embryo is apparently a little longer than its developmental age would allow because its natural curvature is less, perhaps from having had the amnion removed. Carnegie 6344, sequence 4, X15.

B. A cross section through approximately the middle of the embryo seen in Fig. A. Note the blood islands and vessels in the wall of the yolk-sac and tlfi communication of the latter with the primitive gut of the embryo. The large spaces on either side of the gut are those of the coelom or body-cavity of the embryo. Carnegie 6344, section 3-7-11, X75.
